“…4,5 Since then, critical analysis of the orthopedic literature has become indispensable for orthopedists and hand surgeons who require evidence from studies of good methodological quality. In addition, many steps have been taken to disseminate the EBM concepts that apply to the particular characteristics of orthopedics, 6,7 along with critical appraisal of the methodological quality of published studies. 3,[8][9][10][11][12][13] In accordance with this paradigm, efforts have been undertaken within hand surgery to follow the EBM movement.…”

CONTEXT AND OBJECTIVE: There is no systematic assessment of the quality of scientific production in the specialty of hand surgery in our setting. This study aimed to systematically assess the status of evidence generation relating to hand surgery and to evaluate the reproducibility of the classification method based on an evidence pyramid. RESULTS: A total of 1,150 articles were evaluated, and 83 (7.2%) were included in the final analysis. Studies with evidence level IV (case series) accounted for 41 (49%) of the published papers. Studies with evidence level V (other studies) accounted for 12 (14.5%) of the papers. Only two studies (2.4%) were ranked as level I or II. The inter-rater reproducibility was excellent (k = 0.94). CONCLUSIONS:Hand surgery articles corresponded to less than one tenth of Brazilian orthopedic production. Studies with evidence level IV were the commonest type. The reproducibility of the classification stratified by evidence level was almost perfect.RESUMO CONTEXTO E OBJETIVO: Não há uma avaliação sistemática da qualidade da produção científica na especialidade de cirurgia da mão em nosso meio. Este estudo objetiva analisar o status da geração de evidências em cirurgia da mão, por meio de avaliação sistematizada, além de avaliar a reprodutibilidade da classificação baseada na pirâmide das evidências. TIPO DE ESTUDO E LOCAL: Estudo secundário realizado pela Universidade Federal de São Paulo (Unifesp) e Faculdade Estadual de Medicina de Marília (Famema).MÉTODOS: De forma independente, dois pesquisadores promoveram uma busca eletrônica dos trabalhos envolvendo cirurgia da mão, no período de 2000-2009, para duas principais revistas na literatura ortopédica nacional (Acta Ortopédica Brasileira e Revista Brasileira de Ortopedia). Os trabalhos identificados foram subsequentemente classificados pelo tipo de delineamento metodológico (revisões sistemáticas da literatura, estudos clínicos randomizados, estudos de coorte, estudos caso-controle, séries de casos e outros estudos) e nível de evidência (I a V). RESULTADOS:Foram avaliados 1.150 artigos, sendo 83 (7,2%) considerados para a análise final. Estudos com nível de evidência IV (séries de caso) correspondem a 41 (49%) das publicações. Estudos nível de evidência V (outros estudos), corresponderam a 12 (14,5%) da amostra. Apenas dois estudos (2,4%) foram identificados como nível I ou II. A reprodutibilidade interobservadores foi excelente (k = 0.94).CONCLUSÕES: Os artigos de cirurgia da mão correspondem a menos de um décimo da produção ortopédica nacional. Estudos nível de evidência IV foram os mais encontrados na literatura nacional. A classificação estratificada por níveis de evidência apresenta reprodutibilidade quase perfeita.

“…Systematic reviews are a summary of the literature that addresses the available data and promotes the acquisition of rational information for clinical decisions. [13][14][15] The aim of this survey is to promote a systematic review to answer the following clinical questions: 1) Which is the rate of post-NCE complications? 2) Which is the contribution of patellar complications in this population?…”

Non-conventional endoprostheses (NCE) are frequently used in orthopedic oncology. The complications associated with this procedure have prompted research, due to the fact that it is commonly performed on young patients, with a higher survival rate. We conducted a systematic review of the literature, searching for the best scientific evidence on the subject. The research was carried out in the following databases: MEDLINE, EMBASE, CINAHL and the Cochrane Central Register of randomized controlled trials (CCTR), seeking to identify studies that report complications, and compare patellar resurfacing versus retention. The studies were selected according to the Article received on 9/5/09 and approved on 5/27/10 best methodological quality that exists for the subject. One hundred and forty six (146) studies were evaluated. No randomized clinical trial was found. We conducted a qualitative and quantitative evaluation of the work found (evidence levels IV and V). We used the Mann-Whitney U test for the statistical analysis. The results indicate a need for further studies that will enable us to reach a more solid conclusion. The rate of complications after NCE can be considered high, despite the low quality of the studies, as demonstrated by the studies that exist in the literature.
